decide D-87 (output/log dock) + resolve Q-28; file T-258 (terminal home)

D-87 — T-54's "output and log panel" is a bottom output dock: read-only,
two tabs (Output = the Logger stream, filterable + auto-scroll; Problems =
diagnostics moved out of the sidebar). Toggled by a single status-bar widget
that replaces the app-status indicator (merged health+log: green check when
clean, warn/error counts otherwise) via click or Cmd/Ctrl+J. Needs a bounded
ring sink on the Logger (no history today). Amends D-47: the dock is the one
surface allowed to push Claude up, capped so Claude stays >=50%.

Resolves Q-28 by splitting on interaction: read-only output (logs/problems)
goes in the dock; the terminal does NOT — it stays a first-class editor-pane
surface, tracked by new T-258 (swap-vs-split, with Q-27). Refines T-54.
